Somebody has leaked CVE-2026-109618 and CVE-2026-109619 in PHP before the patch is out.

Also hp system management homepage (installed on HPE Proliant servers) all ship with PHP.. with no ASLR. There doesn’t appear to be a patch for that, you can use it to surf around flat networks as it drops you as SYSTEM/root.
@GossiTheDog does HP still restrict firmware updates to active service contract holders for their servers? Because that was one thing that made me decide that I’d never recommend or purchase HP servers.

If you use Palo-Alto firewalls, make sure you upgrade for the PHP vulns.
In particular, if you have the mgmt interface facing the internet upgrade those now. The Palo-Alto firewall VMs have ASLR disabled which makes exploitation trivial.
@GossiTheDog at least all the consumer routers out there based on openwrt are unlikely to be affected - pretty sure PHP has never been part of that stack and I doubt companies using it as a base rewrote it fully in a new language.

@GossiTheDog upgrade to what? Versions with fixes are still pending aren’t they?
-
A really good mitigation for this btw - AppArmor or SELinux.
Google something like apparmor restrict php from executing commands. Works against these CVEs.
Sucks for cybersecurity vendors who shipped their appliances using PHP without SELinux or AppArmor, of course.

For anyone else looking for PaloAlto's notice, it's here:
https://security.paloaltonetworks.com/CVE-2026-109618I'm waiting for it to say something other than ETA: TBD
Had a hard time finding it initially because google wants to send you to their unit42 writeup that covers their take on them protecting you from everyone else instead.

@GossiTheDog wasn’t that on Gen9 servers only which are EOS anyway? That was always the first thing I uninstalled on all machines

There’s absolutely shit tons of exploits for PHP2Shell on GitHub and basically none of them actually work to RCE as nobody can figure out ASLR properly.
Which is good, because patching is going to take a long time.

ASLR supporting PHP exploits are coming, probably next week.. but it’s a really good security control (from decades ago) you should demand your vendors actually enable as it enabled time for orgs paying attention to patch.
The cybersecurity vendor industry itself is essentially negligent when it comes to this stuff. https://infosec.exchange/@catc0n/117487878549556020

https://php2shell.censys.com/@GossiTheDog neat page, though it just assumes versions like 7.4 are unfixed, whereas probably many are using Sury’s PHP which definitely patched it (and I think even 5.6).
There’s probably no better way though to track, so still a useful infographic

@GossiTheDog That toot says there's already a functional ASLR bypass poc out there...?

@mig5 yeah if has clarifications for version numbers not being a bulletproof way. But still, orgs historically very bad at patching so it gives a rough indicator picture. Many are just on raw EOL versions, can also see they’re on EOL Redhat etc.

@christopherkunz there’s one on GitHub but it’s not super functional in reality.. plus people largely haven’t found it yet
it’d need more work to scale. -

@GossiTheDog Wondering why Colin is having such a strong opinion here. He is quite knowledgeable on good security tradeoffs usually. Purism ?

@GossiTheDog it's like saying
"Why wear a seatbelt, if you have a head on, you'll probably die anyway"

It would be easy to dismiss it as security by obscurity, though it's more than that it's akin to the obfuscation of code.
The difference is that the layout of addresses should be random each time it's launched.
But like anything identify the mapping and it's another exercise in lookups.
